Abstract: An isolator comprises an enclosure member adapted to provide a controlled microbiological environment and having a transfer port for passage of objects into and out of the enclosure member. The transfer port comprises a conduit communicating at one end with the interior of the enclosure member, and having its other end external to the enclosure member, and air supply means communicating with the conduit to direct a flow of sterilised air over the inner surface of the conduit. Preferably the conduit has an inner wall and an outer wall spaced apart over at least part of the conduit, and there is provided an array of openings distributed over the inner surface of the conduit.
